what is the reason why the coins of Brazilian real looks the same like the Euro Coins?
the brazilian coins are only s bit bigger, but they look very identical--Hijodetenerife (talk) 00:43, 7 October 2015 (UTC)


 * I'm not so sure they look "identical", but here are File:1 Real Brasil 2007.jpg and File:Common face of one euro coin.jpg. ←Baseball Bugs What's up, Doc? carrots→ 01:33, 7 October 2015 (UTC)
 * The Turkish 50 kuruş and 1 ₺ coins are similar to Euros as well. 62.56.64.211 (talk) 12:00, 10 October 2015 (UTC)
 * The only real similarity is size and the two-tone effect. I think this is more a case of 'convergent evolution'.  There are perhaps 500 to 1000 different coin designs in circulation around the world - and there are only so many ways to have them look, so I'm sure you can find DOZENS of coins with broadly similar designs.  For example, the UK two pound coin is also kinda similar to the Brazilian and Euro coins.


 * There are only a small range of sizes for coins that are large enough to handle conveniently but not so heavy that they weigh down pockets - so it's not too surprising that their sizes would be similar. Two-tone coins are a nice way to suggest higher value than single-color coins - and with the trend to eliminate paper money, it's inevitable that more countries will do that.  There are Russian coins that have the gold color in the center and silver on the outside...but those are really the only two options - so it's kinda inevitable.

 * They appear to be using the same font style for the number, which probably makes them superficially more similar than they really are. ←Baseball Bugs What's up, Doc? carrots→ 14:46, 7 October 2015 (UTC)


 * All the machines, tooling and designs are now done by just very few companies. EG. Schuler. They do everything right down to the design. The previous traditional look of the original coins of any particular sovereign state has thus, vanished into oblivion. Look at all those countries that still have their banknotes printed by De La Rue.  They all look like they came out of the same stable (typographically) – because did! So as with modern coinage. Also, two-tone coins were introduced to make counterfeiting more difficult. In the days before cheap steel was used to increase a state's Seigniorage it was not realy profitable to counterfeit coins with alloys that gave the same weight for their size. I haven't seen a modern US Quarter  for some years now but they had a two-tone milled edge for the same reason. --Aspro (talk) 13:20, 7 October 2015 (UTC)
 * The US coins that were formerly silver are now (since 1964) made of a sandwich whose middle layer is copper. I don't think the two-tone effect was a desideratum. —Tamfang (talk) 00:00, 8 October 2015 (UTC)

Wait a minute, you are only discuss about the 1 Real coin and the 1 Euro coin, I wanted to say, that the 1 cent, 2 cent, 5 cent also look identical to 1 centimo 2 centimo 5 centimo coins and the picuture with the 1 euro is really bad made, the 1 euro coin has a more Gold-Silver color and not like on this picture yellow-white. Use better google pictures to compare them--Hijodetenerife (talk) 20:14, 7 October 2015 (UTC)


 * According to this page, the first coins actually minted in Brazil were struck in 1994, so it's plausible that they either had help from a European mint or that the dies were actually made in Europe. An example of this is that the Royal Mint in the UK still mints coins for less developed Commonwealth countries and before WWII, made the dies for the mints in Canada and Australia. However, we wisely steered clear of those funny Euro things, so it wasn't us in this case. Alansplodge (talk) 16:58, 8 October 2015 (UTC)


 * The Canadian $2 "toonie" also has a 2 tone design. It's actually made of two different metal slugs, though.  Are the Euro and Real ? StuRat (talk) 04:27, 9 October 2015 (UTC)


 * As I said above, very few companies make minting machines and those that do supply a complete package of services. European coins are struck by equipment designed and manufactured by Schuler. Who supply these services to which ever county is willing to buy the latest minting technology. As you can see in this Getty Image: Brazil's national mint. They have bought into European Schuler minting technology rather than try to reinvent the wheel all by themselves. It makes economic sense. So the coins look very similar because they are both out of the same stable. This standardization helps because coin vending machines and coin counters in banks, supermarkets etc, don't have to be redesigned for every country that they are exported to. Therefore, the similarity is by no means a coincidence.--Aspro (talk) 11:38, 9 October 2015 (UTC)
 * Apologies Aspro, I didn't read your post as carefully as I should have done. Alansplodge (talk) 11:48, 9 October 2015 (UTC)

So the EZB in Frankfurt Main has copied the Coins of Brasil? --Hijodetenerife (talk) 08:10, 10 October 2015 (UTC)


 * No. It means Casa da Moeda do Brasil has adopted German coin minting technology. Therefore, `Brazilian coinage looks very similar to European coinage and has similar metallic signatures and design features. --Aspro (talk) 18:29, 10 October 2015 (UTC)


 * how could they adopted german coin mining technology if in germany wasn´t planned a Euro when brazil has given out there money? --Hijodetenerife (talk) 03:03, 11 October 2015 (UTC)


 * Chronology: Modern European coinage technology is now predominate in many sovereign states. It comes down to economics. Mexican, Brazilian and other mints followed these advancements. Coin minting presses for the entire world. Just as the Ancient Chinese developed, printed money, (and gunpowder, bone- china and other stuff) before the West. The West is also now exporting its intellectual knowledge and know-how abroad. Even the modern day  Chinese use Schuler technology – as it is better than trying to reinvent the wheel. The Casa da Moeda do Brasil would not adopt anything unless it had already been proven.--Aspro (talk) 13:13, 11 October 2015 (UTC)
 * I have to make a factual correction - bone china was invented in 1748 by Thomas Frye. Chinese porcelain has similar properties, but is manufactured by a different process. Tevildo (talk) 17:27, 11 October 2015 (UTC)
